9 Claims.

Our invention relates to photographic lm mounting' and more particularly to an apparatus for cutting and mounting selected film frames.

One of the objects of our invention is to provide a unitary device for effecting all the operations necessary to cut selected lm frames from a reel, accurately transfer said frames to a photographic mount and seal said mounts whereby they are ready to beprojected. Thedevice thus offers a mechanical and thereby positive action which eliminates theV uncertainty attendant with the former manual operations and insures a perfect Aresult with a minimum of time and attention.

Another object of our invention is to provide an apparatus for mounting relatively small film such as that of the 16 millimeter size while controlling and insuring the most accurate centering of such lm frames in a mount.

Other objects of our invention will be apparent from the following description, it being. understood that the above general statements of the objects of our invention are intended to explain and not to limit it in any manner.

The film reel I5 has wound thereon lm frameswhich have been 'inspected and marked by a procedure described in a co-pending application led February 8, 1941, Serial No. 378,108, although said procedure is relevant hereto only in that selected frames are properly identified and any other means of identification may be used.

The film strip 6 is unwound slightly from the reel I5 and is manually inserted under the plate I1, while the knurled knob I8 of sprocket drum I9 is manipulated. When the teeth of sprocket drum I9 mesh with the usual marginal perforations 20 of the film strip, the device is ready for operation. Y

As the knob 'I8 is turned, the film I6 is fed under the platev I 1y and emerging therefrom travels over the four pins 2| which slightly engage the four marginal perforations 20 of each lm frame during the travel of the film I6. The pins 2| are rounded and while engaging the perforations 20, as aforesaid, do not appreciably impede the free movement thereof since continued manipulation of the sprocket drum I9 forces the lm forward in spite of the pins 2|. The lpins 2|, however,

serve to center the film frames so that they may into four apertures in the arm 24a of transposer y 24 so that the normal position of the pins 2| is within and protruding from said apertures, as

shown in Figs. 2, 4 and 5.' A metal strip 25, connected to the vunderside of the surface of body portion I0 functions as a back stop and support by pivoting the cutter C about its hinge 26 con- The device comprises a body portion I0 upon whose surface the cutting and mounting operations takes place, and a cover member II, hinged to said body portion. The cover member Il may be advantageously provided with compartments |.Ia for housing mounts, films, etc.

nected to the body I0.

The cutter C comprises a flat plate 21 which is U-shaped centrally thereof in cross-section forming the parallel knife blades 28 which are spaced apart exactly the width of two lm frames for reasons to be hereinafter set forth. Secured to the plate 21 and disposed between the knife blades 28 is a spring finger 29.

The transposer 24 is U-shaped viewed planarly, and one of the arms thereof 24a bears the film frame to be mounted. The other arm 24h functions as a handle facilitating the pivoting of ihe transposer 24 about its hinge 30.

r Formed in the upper surface of body II) is a recessed bed 36 within which is placed the card mount 3| which will receive the film frame now maintained by pins 2| on the arm 24a of the transposer 24. Said card mount 3|, subject of a co-pending application iiled February 8, 1941, Serial No. 378,109, comprises a folded cardboard or paper and is formed with a peripheral iiap 32, cut from the mount 3| and remaining integral at one edge 33 thereof, forming a recess .in the mount for the reception of the selected film frame. 'I'he iiap 32 is formed with an opening 34 Whose dimensions are exactly` those of the portion of the film frame to be projected while the other side has a ylarger opening 35 formed therein whose dimensions are exactly those of the film frame'plus the marginal'perforations 20,

As seen in Fig. 1, the mount 3| is maintained in the recessed bed 36 by four pins 31, which constitute projections on a member 38 in all respects identical with member 22. The pins 31 irictionally abut the walls of the opening 35 maintaining the mount 3| in position. The member 33 is urged outwardly by a leaf spring 39 secured to the underside .of the surface of body I by rivets 40, so that the normal disposition of the pins 31 is in the projected position.

'I'he flap 32 of the mount 3| is bent backwards so as not to interfere with the transposition of the iilm frame to the mount 3| and the underside of the iiap 32, as well as the surface of the recess which its formation causes in the mount 3|, is provided with rubber cement or preferably, a solution of para rubber in gasoline which has the property of adhering -only to a similar surface without the necessity of meistening. However, any adhesive is operative. Disposed laterally of the mount 3| and adjacent the flap 32 thereof, is a presser plate 4I, hinged as by' a hinge 42 to the upper surface of body I0. Secured to the face of the plate 4| by adhesive or any other suitable meansis a pad 43 of a soft material such as sponge rubber or felt.

Our invention is practiced in the following manner:

Upon the reel l5 is wound the film I6 and we will assume that the selected iilm frames thereon are provided with suitable'indicia. so as to be identifiable upon cursory inspection. The `reel I5 is mounted on the end wall I3 by its bracket I4 and the film I6 isY manually inserted under the plate |1 while, as hereinbefore stated, the` knob 8 is rotated until the teeth of the sprocket drum I9 catch in the perforations 20. Thereprepare the film for the cutting operation and to rmly seat the desired lm frame on the pins 2|. The knife blades 23, following the spring finger 23, sever the desired film frame and such blades 23, being 'spaced two film frames apart, actually sever both the desired lm frame and an additional half frame on each side of the deafter, further rotation of the knob I8 causes the vfilm I6 to travel between the sprocket drum I9 and the plate I1, and emerge over the pins 2| on the arm 24a of the transposer 24. Should the film I6 catch against the arm 24a, slight manipulation of the transposer 24 about its hinge 30 is effective to re-direct the film over the pins 2|.

As the film travels over the pins 2|, which at` this time serve to provide a definite stop means as the perforations 20 are slightly engaged by the pins 2|, the operator notes a iilm frame which has been marked for mounting. After noting that such desired frame is engaged by the pins 2|, he severs the film frame from the film I6 by operating the cutter C. A slot 44 formed on the upper surface of the body i0 is usually effective in catching and disposing of the cut front and unused portion 45 of the film, as noted in Fig, 5.

As the cutter C is swung by the operator to sever-the desired illm frame, the spring finger 29, preceding .the knife blades 28 (Fig. 2), pushes the iilm well down on the pins 2| so as to both sired frame (Fig. 8). The additional half frames thus serve as margins permitting the subsequent retention of the film frame in the mount 3|. As the cutter C is retracted, the spring finger 23, continues to bear against the severed film frame until the blades 23 are swung away, so that the retraction of the cutter C does not cause the displacement of the severed film frame from its :iat on the pins 2| by adherence -to the blades A mount 3| is placed in the recessed bed 36. the opening 35 of the mount embracing the pins 31 which thus retain'the mount in place. As noted in Fig. 1, the iiap 32 is bent back and overlaps the presser plate 4|.

The arm 24h of the transposer 24 is then pivoted about the hinge 30 and the projecting pins 2| strike and rest upon the pins 31. The leaf spring 23 is so constructed as to be weaker than the leaf spring 33 with the result that continued pressure on the arm 24b causes the pins 2| to withdraw into the apertures of arm 24a thus releasing the severed film portion. 'I'he pins 31, remaining upstanding, are caused to enter the perforations 20 upon the withdrawal of the pins 2| so that the result is the transfer of the severed iilm portion onto the pins 31, which thereafter retain said film portion as illustrated in Fig. 6. The transposer 24 is then pivoted back to normal position and the presser plate 4| is pivoted about the hinge 42, whereupon the flap 32 is urged into position and the adhesive takes effect sealing the mountwhile the iilm is positioned on the pins 31. Depression of the' presser plate 4| `forces the pins 31 downwardly against the action of the springs 33 and the iiap 32 is therefore enabled tol assume a fiat position within the recess resulting fromits formation. The mountl is therefore perfectly formed with the film frame visible through the opening 34 just as it will be projected, while through the larger opening 35 can be seen the perforations 2 Il. However, the opening 34 eifectively screens these perforations so that they are not seen when the mounted film frame is projected.

When the presser plate 4| is swung back into normal position, the pins 31, returning by virtue of the spring 39, may again enter the perforations 20, but contacting the underside of the flap 32, cause the mount 3| to be lifted, whereupon the mount may be easily removed by the operator and the entire procedure repeated for further mounts.

While the procedure as detailed herein appears rather complex, in actual practice it is surprisingly simple and quick, the time consumed in mounting a desired film frame being but a poser, and a cutter member for severing a desired film frame from' said length of film while said nlm frame is located on said transposer, said transposer being operative to deposit said severed film frame in a mount.
